```
A programmer is creating a simulation of a city where natural disasters can
randomly occur.
This incomplete code segment simulates a Godzilla disaster:
IF (
```)
{
cityHealth - cityHealth - 30
disasterMode - "godzilla"
}
The code should only give Godzilla a 2% chance of storming the city.
Which of these can replace so that the code
works as intended?
Choose 1 answer:
A
RANDOM (1, 100) <= 2
B
RANDOM (1, 100) >= 98
RANDOM (1, 100) <= 98
C
RANDOM (1, 100) >= 2
D

Explanation

The problem requires determining the correct condition to use in an IF statement to simulate a 2% chance of a Godzilla disaster in a city simulation.

Step-by-step Instruction

▪

Identify the correct condition: The RANDOM function should generate a number between 1 and 100, and the condition should be true for 2 out of those 100 numbers

▪

Evaluate the options: Check which condition correctly represents a 2% chance

Time Complexity

The time complexity of evaluating a condition in an IF statement is O(1).

Space Complexity

The space complexity is O(1) as no additional space is required.

```
Let's evaluate the given options:
1.
```

```
- This condition will be true if the random number generated is 1 or 2.
- Probability: $\frac{2}{100} = 0.02$ or 2%.
2.
```

```
- This condition will be true if the random number generated is 98, 99, or 100.
- Probability: $\frac{3}{100} = 0.03$ or 3%.
3.
```

```
- This condition will be true if the random number generated is between 1 and 98.
- Probability: $\frac{98}{100} = 0.98$ or 98%.
4.
```

```
- This condition will be true if the random number generated is between 2 and 100.
- Probability: $\frac{99}{100} = 0.99$ or 99%.
The correct answer is
```

```
.
Here is the code snippet with the correct condition:
```

python

Explanation

The code simulates a 2% chance of a Godzilla disaster by using the condition "RANDOM(1, 100) <= 2".

Time Complexity

The time complexity of the simulation is O(1) for each run.

Space Complexity

The space complexity is O(1) as no additional space is required.
